SAFETY RAZOR Filed March 13, 1931' Patented Jan. 5, 1932 WILLIAM FELSER,0F BALTIMORE, MARYLAND SAFETY RAZOR Application led March 1'3, 1931.Serial No. 522,373.

This invention relates to improvements in safety razors and moreparticularly to a novel and improved blade adjustment for safety razorsof the Gillette type.

With the Gillette razor it is possible to adjust the blade edgesrelative to the guard for a light or close shave. It is the practice ofmany men in shaving to go over the face twice-first, for a light shavewith the blade edge close to the guard, and the second time for a closeshave, with the blade edge spaced from the guard.

The object of this invention is to provide a positive means whereby theangularity of the blade may be readily adjusted so that the desiredshave may be obtained.

A further object of the invention is to provide a simple and inexpensivemeans for locking the blade in the adjusted position.

With the above and other objects in view, the invention consists of thecombination and arrangement of parts hereinafter to be fully describedand claimed.

ln the accompanying drawings forming a part of this specification Figure1 is an elevation of a razor of the Gillette type embodying theinvention.

Figure 2 is an elevation with part of the razor broken away.

Figure 3 is a modified form of the invention showing locking means forthe adjusting means. y

Figure 4.- is a'view of the adjusting nut or handle. j

Figure 5 is a View of a modified form of the internal threaded portionof the handle.

Figure 6 is a. modified form of the locking bar.

Referring to the drawings in detail wherein like reference charactersdesignate corresponding parts throughout the several views, 10designatesthe top or head portion with a threaded stud extending thcrei'rom which is adapted to pass through a central aperture in the razorblade guard 11. Between the blade guard andthe head portion ispositioned blade 13 which becomes flexed when the internally threadedhandle or stem 12 is screwed into position against the lower face of theguard.

Under ordinary circumstances as the head ortion isv urged toward theguard, the blade is flexed andthe angularity 1s changed until guard andhead. lVhen usine` a safety razor there can not be obtained diflerentangles by tilting the handle but it is necessary to tilt the bladeitself which can be accomplished by tightening or loosening the handlewhich results in theengularity of the blade being changed. When thisadjustment is made, the upper part of the razor, that is, head 10, guard11, the blade 13 are not firm in respect to the handle 12 as the tensionon the blade is not suiiciently strong to hold the upper part of therazor in a solid unit during shaving. The upper part of the handle has atendency to turn which not only changes the proper angle of the bladebut also often results in cutting of the face. ln order to obviate thisdanger and to hold the blade in the desired position after theadjustment has been made, I pro vide means for locking the razor in theadjusted osition.

The andle 12 is internally threaded and the lower end of the handle isopen and locking bar which is threaded at 16 is adapted to be insertedinto lthe'handle 12. On the outer end of the bar 15 is a handle or knob14 which is preferably knurled on its eripheral surface to facilitatehand turning of the locking bar.

After the blade has been adjusted to the required angularity the lockingbar 15 is screwed into the handle 12 until the end of the bar 15 comesinto contact with the threaded stud extending from the head portion 10,this will hold the unit in the adjusted position and will insure thatthe upper part of the razor will not turn or get out of adjustment.

y Figure 3 is a modied form of the locking bar 15l in which the handle14: has a pin 19 extending therethrough. The pin/is adapted to bevinserted into one ot a plurality of apertures 22 to lock the locking bar15 in the adjusted position. Pin 2O has a head or handle 23 i'ornied onthe end thereoi` and around the pin 19 is a spring for holding the pinin one of the holes 22.

Figures 5 and 6 show modiiied forms of 4the blade conforms to thecurvature of the the locking bar 15 and the internally threaded portionof the handle 12. The handle 12 in the modified form has interruptedthreads formed at 21 and the pin 15 has interrupted threads formed at18. The use of interru ted threads in the handle 12 and on the loc ingbar 15 will permit of a rapid adjustment and locking of the razor in thedesired position.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is,-

1. In a safety razor, a guard, a member for coacting with said guard toclamp a blade thereto and having a stud projecting through the guard toadjustably secure the blade in place, a bar for locking the blade in theadjusted position and means for securing the locking bar in the desiredposition, said means including a spring pressed pinsecured on one end ofsaid locking bar.

2. A safety razor comprising a head, a guard, an internally threadedstem, a series of openings in one end of said stem, said head portionhaving a threaded stud adapted to pass through the guard and into thethreaded. stem whereby a razor blade may be lexed against the guard, andan adjusting screw in the stem, one end of the adjusting screw adaptedto lock the blade in the adjusted position, one end of the adjustingscrew provided wth a pin for cooperating with the series of openings insaid stem for locking the adjusting screw in the desired position.

3. in a safety razor, a guard, a member coacting with said guard toclamp a `blade thereto and having a stud projecting through the guard toadjust the angularity of the blade, a hollow handle having a partthereof internally threaded, of a locking bar extending into said handlefor securing the blade in the adjusted position and a pin member on saidlocking bar for holding the locking bar in the desired position.

4. A safety razor comprising a head, a guard, an internally threadedstem, a series of openings in said stem, Said head portion having athreaded stud adapted to pass through the guard into the threaded stem,an adjusting bar in the stern for locking the blade in the desiredposition, and a spring pressed pin carried by said adjusting bar, forcooperating with said series of openings for locking the adjusting barin the desired posilon.

5. In a safety razor comprising a hollow handle having an internallythreaded portion, a head adapted to receive a. blade, a threaded studextending from said head, a guard for co-acting with said head portionto clamp a blade in place, a locking bar having interrupted threads isadapted to extend into said hollow handle, and spring pressed lockingmeans on one end of said locking bar for securing the bar in the desiredposition.
